Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional software recording is used to track glass substrate entry and exit from high temperature cavity, then detection coverage is provided, but detection timeliness deteriorates due to delayed recording updates
Solution Approach 1:
The patent replaces the software-based recording system with a mechanical deflection probe system that physically contacts the glass substrate. This mechanical detection method provides immediate, real-time feedback when the substrate enters or exits the high temperature cavity, eliminating the time delay inherent in software recording updates while maintaining accurate detection of substrate presence.
Solution Approach 2:
The deflection probe system is self-activating through direct physical contact with the glass substrate. When the substrate enters the detection zone, it automatically triggers the probe deflection and subsequent electrical signal generation without requiring external recording operations, ensuring immediate detection and eliminating dependency on periodic software updates.
2Adaptability or versatility
If thermo-stabile elements are used for detection in high temperature cavity, then detection capability in high temperature environment is achieved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the detection function from the high temperature environment by positioning the detection elements (grating sensor or pressure sensor) outside the high temperature cavity. Only the deflection probe, which can withstand high temperatures, is placed inside. This separation allows the use of conventional, simple sensors without requiring complex thermo-stabile detection elements.
Solution Approach 2:
The deflection probe serves as an intermediary between the high temperature environment and the detection elements. It transmits the physical contact information from the glass substrate through the cavity wall via the seal bearing to the sensors located in the safe, low-temperature zone, enabling detection without exposing sensitive components to high temperatures.
3Loss of time
If deflection probe is passed through cavity wall for detection, then real-time detection is achieved, but cavity sealing integrity deteriorates
Solution Approach 1:
The seal bearing performs multiple functions simultaneously: it provides rotational support for the deflection probe, maintains the sealing integrity of the high temperature cavity, and enables the probe to rotate freely for detection while preventing gas leakage. This multi-functionality resolves the conflict between detection capability and sealing integrity.

The solution reduces errors in manufacturing processes by providing real-time detection of glass substrates within the high temperature cavity, minimizing material mismatches and lowering development costs through precise detection with conventional sensors.
Implementation Method 1
the deflection probe will be connected with the detection element, the detection element will send out a electrical sensor signal
Implementation Method 2
When the grating sensor is used to be the detection element, the grating sensor comprises a light emitter, a contact probe and a light receiver, wherein the light emitter and the contact probe are connecting with together, when the glass substrate is touched by the deflection probe, the light emitter can be connected with the deflection probe by backswing, and then the intensity of the light source will be reduced and a light sensor signal will be transformed into a electrical sensor signal to send out
Implementation Method 3
When the pressure sensitive sensor is used to be the detection element, the contact probe is reach out from the front end of the pressure sensitive sensor, with the glass substrate touching the deflection probe, the pressure sensitive sensor can be connected with the deflection probe by backswing, if the present pressure is larger than the presetting pressure, then the light sensor signal will be transformed into the electrical sensor signal to send out
